Grilled Beef Skewers

Ingredients

• Beef sirloin (1.5 pounds, cut into 1-inch cubes)
• Red onion (1 large, cut into wedges)
• Bell peppers (2, cut into 1-inch pieces (any color))
• Olive oil (1/4 cup)
• Lemon juice (2 tablespoons)
• Garlic (3 cloves, minced)
• Cumin (1 teaspoon)
• Paprika (1 teaspoon)
• Salt (1 teaspoon)
• Black pepper (1/2 teaspoon)
• Wooden skewers (8, soaked in water for 30 minutes)

Instructions

1. In a large bowl, whisk together the olive oil, lemon juice, minced garlic, paprika, cumin, salt, and black pepper to create the marinade.
2. Add the beef sirloin cubes to the marinade and toss to coat evenly. Cover the bowl with plastic wrap and refrigerate for at least 1 hour, or overnight for deeper flavor.
3. Preheat your grill to medium-high heat, ensuring it's well-oiled to prevent sticking.
4. Thread the marinated beef cubes, red onion wedges, and bell pepper pieces onto the soaked wooden skewers, alternating the ingredients for an appealing presentation.
5. Place the skewers on the grill and cook for 10-12 minutes, turning occasionally, until the beef reaches your desired doneness (medium-rare is approximately 135°F).
6. Remove the skewers from the grill and let them rest for a few minutes before serving.
